iOS Developer & Tech Lead

Tech lead by day, indie maker by night. Building native iOS apps that solve real problems with over 10 years of experience and a passion for Apple platforms.

About Me

With over 10 years of iOS development experience, I've journeyed from junior developer to tech lead, currently leading a team of 20 iOS developers. My background spans from Unity game development (where I founded unityspain.com) to mastering Swift and modern iOS architecture.

My indie apps like Boxy, Undolly, and Numly all started from personal needs. I believe the best apps solve real problems you've actually experienced.

From Guadalajara to Barcelona, I'm passionate about making the most of Apple platforms and staying at the cutting edge of iOS technologies. I've spoken at a couple of conferences like NSSpain and OMT about iOS development challenges.

My Apps

iOS applications I've designed and built from concept to App Store, each solving real problems with elegant, user-friendly interfaces.

Numly

Numly

Bullet journal meets digital

As a bullet journal user, I struggled to save links on paper that I could open digitally. Write #42 in your notebook, then open it instantly on your Mac, iPhone, or iPad. The perfect bridge between analog and digital.

Boxy

Boxy

Born from moving day chaos

Born from moving day chaos. Organize your physical items digitally using boxes and categories. Now my father organizes his tools and I organize everything with NFC magic.

Undolly

Undolly

Because other apps overwhelmed me

Created because existing gallery cleanup apps overwhelm you with thousands of photos or do not explain why one image is better. Undolly shows you small groups and tells you exactly why to keep each photo.
